## What is number of electric lines of force?

The electric lines of force are represented by the equation x2+y2=1. A unit positive charge initially at rest at point (1,0) will move.

## What is the number of electric lines of force that radiate outwards from 1c charge in vacuum?

The number of lines of force radiating outwards from one Coulomb charge is (2) 1.13.

## What is a electric line of force?

The electric lines of force that represent the field of a positive electric charge in space consist of a family of straight lines radiating uniformly in all directions from the charge where they originate. A second positive charge placed in the field would travel radially away from the first charge.

1.13*10^12.

## How do you find the number of lines of force?

Concept: Gauss law. The number of lines of force originating from a charge of 1 C is equal to the Electric flux through a closed surface enclosing a charge of 1 C . N = q/EoN = 1/8.85 × 10^-12N = 1.29 × 10^11.

## What is SI unit of electric flux?

Electric flux has SI units of volt metres (V m), or, equivalently, newton metres squared per coulomb (N m2 C1). Thus, the SI base units of electric flux are kg·m3·s3·A1.

## What does it mean when electric field lines are close together?

A line tangent to a field line indicates the direction of the electric field at that point. Where the field lines are close together, the electric field is stronger than where they are farther apart.

## What is the importance of electric line of force?

An electric line of force is the path along which a unit positive charge will move inside the electric field, if it is free to do so. The importance of electric line of force is that the tangent at any point to it gives the direction of electric field at that point.

## What happens when an electron is placed in an uniform electric field?

Hey. Here is the answer. As the electric field is directed from Positive (+ve) to negative ( -ve) and the negatively charged electron gets attracted to the opposite charge (i.e., positive) and the electron moves in the direction opposite of the electric field towards the +ve.

## Which lines of force is possible?

1. Field lines point in the direction of the electric field . Field lines cannot cross. If two lines did cross, then the force on a charge would have two directions, which is impossible.

## What is electric field lines and its properties?

An electric field line is an imaginary line or curve drawn from a point of an electric field such that tangent to it (at any point) gives the direction of the electric field at that point. Properties : 1. Electric field lines starting from positive charge and terminating at a negative charge.

## Do electric lines of force have physical existence?

Each electric lines of force is conceptually imagined it does not have any physical existence. Total number of lines of force emanated from a charge body is equal to the charge of the body measured in Coulomb. … No lines of force can exists inside the conductor.
